Letters Patent N 96,753, dated November 9, 1869.

IMPROVED WINDOW-SCREEN AND BLIND.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it knownthat I, BE vJA'MIN J. IVILLLxns, of the city and county of Philadelphia, and State of Pennsylvania, have invented a new and improved Combined Window-Screen a-ndVenetian Blind; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in whieli Figure l is an inside view of screen and blind combined, when adjusted to window.

Figure 2 is an outside view.

Figure 3 is a detailed view of groovcd strip.-

Figure 4 is an edge view of screen.

Like letters, in the figures of the drawings, indicate like parts.

My invention, B, relates to the class of adjustable window-screens for excluding mosquitoes and other insect-sfrom houses; and consists of a stationary screen, with supplemental screens, constructed and operating the same asin invention A, but having combined therewith Venetian blinds, so that the admission of air and light into the room may be regulated without the inconvenience oi' .removing the screen to accomplish it I by the outside blinds; and even then it cannot always be done, as many outside blinds have fixed slats, and so with inside panel-shutters, where but few pivotslats are used.

The object, therefore, of usingVenetiau blinds with a window-screen is to remedy this inconvenience.

I construct and operate my invention as follows:

A is the stationary screen.

B B, supplemental screens, movable in guides a a, attached to top and bottom of stationary screen, and having tongued edges b b, to fit grooved strips C, which will be screwed to the beads of the windowjambs. These strips will extend up to the meetingrails of the sash, o r up to the top of the windowframe, so that a screen may be used ateither top or bottom of window.

D D are the Vcnctian blinds, hinged in a proper manner to the inside of the side bars of the frame, so that they will come flush with the inner edges of the bars all around when closed. v

The supplemental screens are provided with fixed slats c. 4 f

lhe stationary screen has set-screws (l, (the same as in the patent of D. 1I. Hurlburt, June 1, 1869, No. 90,845,) for fastening the supplemental screens when the whole is adj usted to t the window, and also buttons e e, forasteuing the blinds.

In fitting the screen to the window, the stationary screen is placed on the sill of the frame, leaving an equal space on either side for the proper adjustment of the supplemental screens, which are moved out until they fit the gi'ooved strips snugly, when the setscrews are tightened, and the whole thus fastened to the window. l

The advantages/as stated in invention A are, that the screen thus constructed can be adjusted not only to any window of ordinary width, but can be adjusted as well at the top as at the bottom of the'wiudow, without inconvenience of removing and replacing pins when fastening screen, as heretofore, and at the same time the Venetian blinds afford the requisite means-by which the admission of air and light may be regulated.

Having thus fully described my invention,

What I claim therein as new, and desire to secure by Letters Patent, is v The combination of Venetian blinds D with a stationary or an adjustable window-screen, either with or without supplemental screens B, substantially as described.

As evidence that I claim the foregoing as myinvention, I have hereunto set my hand, in the presence of two witnesses'.
